Description

Technical Field

[0001] The utility model belongs to the technical field of bearings and relates to a combined deep groove ball bearing. Background Art

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support a mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. Therefore, it is widely used in mechanical equipment. Generally, a bearing is used in cooperation with a bearing housing. Due to the long-term operation of the bearing, internal wear occurs in the bearing, resulting in unstable operation and the need for replacement. When replacing, the bearing housing generally needs to be disassembled. In the actual disassembly process, the splicing of the bearing housing is generally carried out through studs. Therefore, during the disassembly process, some impurities may enter the threads. When the threads are assembled, deformation may occur, affecting the service life of the threads. As a result, there may be gaps in the splicing of the bearing housing, affecting subsequent use. At the same time, its disassembly is relatively cumbersome, thus not meeting the use requirements. Summary of the Invention

[0003] The purpose of the utility model is to provide a deep groove ball bearing that is easy to assemble and reduces assembly deformation in view of the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A combined deep groove ball bearing includes a bearing housing and a bearing main body disposed in the bearing housing. The bearing housing is characterized in that it is composed of an upper housing and a lower housing spliced together. On both side walls of the bearing housing at the splicing position of the upper housing and the lower housing, there are splicing units for connecting the upper housing and the lower housing and improving the connection stability.

[0005] In the above combined deep groove ball bearing, on both side walls at the lower end of the bearing housing, there are flanges connected thereto, and assembly holes are provided on the flanges.

[0006] In the above combined deep groove ball bearing, the splicing unit is composed of an assembly block and a splicing block. The assembly block is disposed on the lower housing and connected thereto. The splicing block is disposed on the upper housing and connected thereto. An installation groove for installing the splicing block is provided on the upper end surface of the assembly block. On the side wall of the splicing block that fits with the assembly block, there is a protruding portion that protrudes axially outward and is embedded in the assembly block. On the protruding portion, there is a dovetail block portion connected thereto and embedded in the assembly block through the protruding portion. The height of the dovetail block portion is less than the height of the protruding portion. An assembly groove for installing the protruding portion is provided on the assembly block. On the wall surface of the assembly block at the assembly groove, there is a dovetail groove connected to the assembly groove and for embedding and installing the dovetail block portion.

[0007] Compared with the prior art, the combined deep groove ball bearing has the following advantages:

[0008] 1. On both side walls of the bearing seat at the splicing position of the upper housing and the lower housing, there are splicing units that connect the upper housing and the lower housing and improve the connection stability. The setting of the above structure facilitates its assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following are specific embodiments of the present utility model in combination with the drawings, and the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0012] As shown in Figure 1 , the combined deep groove ball bearing includes a bearing seat and a bearing body arranged in the bearing seat. The bearing seat is composed of an upper housing 1 and a lower housing 2 spliced together. On the end face of the lower housing 2 at the connection with the upper housing 1, there are guide posts, and on the end face of the upper housing 1 at the position of the guide posts, there are guide grooves. On both side walls of the bearing seat at the splicing position of the upper housing 1 and the lower housing 2, there are splicing units that connect the upper housing 1 and the lower housing 2 and improve the connection stability. The splicing unit is composed of an assembly block 3 and a splicing block 4. The assembly block 3 is arranged on the lower housing and connected to it, and extends to the upper housing. The splicing block 4 is arranged on the upper housing and connected to it. On the upper end face of the assembly block 3, there is an installation groove for installing the splicing block 4. On the side wall of the splicing block 4 that fits with the assembly block 3, there is a protrusion 5 that protrudes axially outward and is embedded in the assembly block 3. On the protrusion 5, there is a dovetail block part 6 connected to it and embedded in the assembly block 3 through the protrusion 5. The height of the dovetail block part 6 is less than the height of the protrusion 5. On the assembly block 3, there is an assembly groove for installing the protrusion 5. On the wall surface of the assembly block 3 at the position of the assembly groove, there is a dovetail groove connected to the assembly groove and for embedding and installing the dovetail block part 6.
